Trolling Spoons have an elongated shape and possess one concave side that makes them "wobble" in the water, closely resembling and imitating the action of cripled baitfish. Spoons typically have a painted-on color pattern on one side. Most anglers who utilize these spoons will use special apparatus, such as a downrigger or a diving plane, to keep the spoon at a specific depth as it trails the boat. A trolling spoon should wobble from side-to-side and will produce its best all-around fish catching action when trolled between the slowest possible speed that produces a wobble, and the fastest darting action that does not cause the lure to revolve or spin. Trolling Spoons are great for catching walleye, trout and salmon.
